Its hard to say with the example you provided but I think you should be looking at using textscan

Thanks lestyn

Yeah the output of my message was not clear.

The idea is: I have four lines in my text file, the first and the third are commented (begin with %) and the second and the fourth lines are vectors of integers.

How can i extract the two vectors?

Sermed, textscan is likely the right chose. Read the doc page lestyn indicated, especially the CommentStyle option -- you should be able to ignore lines that begin with a '%'.

by saying lines, do you mean row or column vectors? Either way, try to use dlmread first:

M = dlmread(filename)

so your filename will be the path where the text file is located e.g.

C:\My Documents\textFile.txt

where textFile is the specific name of your text file. If this doesn't work let me know and we can try and think of another method.

Thanks again lestyn

I've tried with dlmread function but it returnes an error statment if the text file included other than integers.

I tried with textscan as well but i managed to read only the first vector.!

Can i send you the text and m.file?

thanks in advance

Sure.
